When you first start Mapper you will see the following screen. It tells you that you haven't created any maps yet and tells you to tap the '+' button if you want to create a new map. That is what we want to do, so tap it now.

A list of buttons will slide up from the bottom of the screen. Press one of the two buttons to create a new map from the source you want to use. You can also press 'Cancel' which will bring you back to the start screen.

When you have selected a scan or photograph of a map, either from your library or your camera, you will see the screen on the LEFT (ofcourse the map image we are using will be different from yours). You will notice a couple of buttons and other gizmos. We will go through them, one by one (notice that they are numbered in the screenshot).

1. This button does what it says and sends you back to the start screen.
2. The 'Done' button (which is grayed out right now) will put you into 'tracking mode'. In that mode, you will be able to see your current position on the map. More on that later in the tutorial.
3. This text field allows you to edit the map's name. You tap it and a keyboard will come up. It is recommended you always change the map's name to something more meaningful than 'Map name'.

Note that you can also move the map around by dragging it with your finger. You can also zoom using the pinching motion. Double tapping the map will zoom you either to a full overview level or it will scale to the pixelscale of 1:1.

It is time to add a 'marker'. Markers are what Mapper uses to get more information about the map. Mapper, by default, knows nothing about your map and you need to teach it where it is in the world and what the scale is. This, however, sounds a lot more complicated than it really is. To place a marker, just hold your finger on the screen. You should see a blue bar under the map's name. After a short while a crosshairs will appear above your finger. The marker will be placed in the circle of the crosshairs. You should place a marker on a nearby, easily identifiable point, like for instance a crossroad.

Now Mapper needs to learn where the position you just indicated is in the world. To do this, simply tap the marker. A couple of buttons will be shown (see screenshot on the LEFT). You should walk, cycle or drive to the location you indicated on the map.* When you are at that position, tap the 'I am here' button. This will make Mapper search for your current location using GPS.

* That is the reason the marker should be placed nearby. If you want to place a new marker, simply delete the old marker and repeat step #4.

Mapper will display an accuracy value. The lower this value is, the better your tracking will be. However, it might take longer to find a more accurate location. Tap the 'Accept accuracy' button when you think the accuracy is good enough. The marker will turn green, indicating that is has been located. Now just press the 'Cancel' button to dismiss the marker's actions.

Now repeat step 4, 5 and 6 to create a second marker. This second marker does not need to be placed very far from you first one, but it shouldn't be at the same location either. You might have noticed that the 'Done' button we talked about earlier, isn't disabled anymore. This means Mapper has enough information to start 'tracking' (showing your location on the map). Tap the done button.

You should now see something similar to the screenshot on the LEFT. Your current position is indicated by the red dot. Try moving around, you should see your position on the map getting updated. Note that there might be a semi-transparent circle around the dot. This indicated the current accuracy. You could be anywhere in this circle.
